Hi all, I picked up a used kevlar canoe from Portage Outfitters (Ontario) last fall. It has some cracked ribs I need to repair. Although I understand the basics of doing this I am wondering about aesthetics. In a perfect world when I'm paddling an empty canoe I would prefer not to see the cracks in the ribs that I have patched. Does anyone have experience with this? Is fiberglass or kevlar going to be a better cover from a viewing standpoint (I appreciate kevlar is stronger); should I consider a double layer? Anyone other than www.rayplex.ca that I should consider for materials if I am ordering from Ontario Can?
